"I love music," was Schmidt's response, and the three men went laughing to bed. Roger wakened in the night but once. Through the open tent flap he beheld Mrs. von Minden rocking silently in the starlight before her tent. "She's going to get on my nerves," he murmured and fell asleep again. Dawn was just breaking over the mountains the next morning when Roger entered the cook tent. He was greeted by Gustav, who was purple with the cold but grinning cheerfully, and the smell of coffee. "It vas not so soft, sleeping on Frau Nature's heart in the desert, nicht wahr!" he exclaimed. "Coyotes vere eating the garbage last night mit gulps and snortings and I slept not. It vas not the music I had been promised. So I make the breakfast early." "I didn't sleep well myself the first night or two," said Roger. "Desert silence makes a lot of noise to a town-bred man. Hey!"--going to the door--"Ern! You lazy Dutchman! The new cook'll leave if you don't get up for your breakfast." Gustav and Roger were half through the meal when Ernest appeared. "Mud-pie making is hard work," he groaned, sliding stiffly onto the bench beside Roger. "I certainly hate to make adobe brick when every day counts so," said Roger. "Let's use sheet iron." "It'll be better to take Dick's advice," insisted Ernest. "He says the dust storms are frightful here and the heat worse. The adobe shelter will be grateful on many counts." "Ve'll all vork hard," said Gustav, "and the 'dobe vill be up strong, before ve know it. Ven it is done, it is done good, and that is right. I vash the damn dishes. You go make the mud mixing. Then I come." "We're going to hate to let that chap go when his visit's up," said Roger, as he and Ernest began work on the adobe. "Maybe we won't have to let him go," replied Ernest. "You stir the mess up, Rog, and I'll put it into the molds. Dick is going on with his grading, but he'll be over in a day or so and show us how to begin the house building." "The trouble with you is, Ern, that you're flighty-minded. You're tired of making a Sun Plant and all excitement over building a mud house." "I wouldn't have a single track mind like yours for a million dollars," returned Ernest cheerfully. Roger grinned and presently began to whistle as he worked. Mrs. von Minden proved to be an exceedingly unexacting guest. After it was evident to her that her hosts had not the slightest intention of doing special cooking for her she did her own. She ate only two meals a day, preparing one at mid-morning and one at sundown. The remainder of the day she spent within her tent, reading or rocking in her chair, concentrating on the camp work. She seldom talked and then only on the matter of what she called Yogi-ism. Gustav took a violent dislike to her and refused to work if she looked at him. Roger declared that on the next trip to town he was going to telegraph Phoenix and see if she had not escaped from an insane asylum. But Ernest only laughed.
